Shortly after suffering a work injury, an injured worker usually receives a call or letter from a claims representative who investigates and processes the claim for the employer's workers' compensation insurance company. Eventually, the insurance company may assign a nurse case manager to the claim. Like the claims representative, the nurse case manager usually calls or sends a letter to the injured employee and may ask the injured employee questions about his or her treatment plans. In addition, the nurse case manager may begin scheduling appointments for the injured worker, attending those appointments, and even speaking with the injured worker's doctors.
